(sorry, I find this somewhat confusing) Inside kernel_init(): * linuxrc is executed first, via prepare_namespace() -> initrd_load() -> handle_initrd() * init_post() happens second, by which time /dev/console must exist So linuxrc gets a chance to create /dev/console even if one doesn't exist in the ramdisk.
